Well, I'm not good at typing sentimentally, but suffice to say, anyone who ever met him is deeply saddened by today's news. He died today (Yesterday now, I guess) from the cancer. I was fortunate enough to meet him a few times, and he was truly one of the greatest minds in the field. :(
If any of you don't know who he is: http://en.wikipedia.org/wiki/Randy_Pausch
(Edit: Yeah, Short post. But, well, most of you probably already knew. I needed google to tell me.)
